STOCKMANS STOVE.

Application filed July 13,

This invention relates to stoves and particularly to stoves which are intended for ready transportation and which are, therefore, compact, relatively light7 and easily handled.

The general object of the present invention is to construct a stove of this character ol' sheet metal and so form the stove that it will be particularly strong` and will not be liable to break or have its joints open.

Another object is to 'provide means for interlocking the metal sheets constituting the side, top and bottom walls ofthe stove so that the sheets will interlock with each other without the necessity of using rivets.

Still another object is to provide corner irons which will protect the corners of the stove and prevent them from being dented 1n.

A further object is to provide a stove comprising an outer casing and an oven disposed within the casing and extending transversely the full width of the casingl and stove from the top and bottom ot' the casing and the Arear wall thereof .so as to permit the products of combustion from the ire box to pass around the oven it necessary and, in this connect-ion, arovide means whereby the products of combustion may be caused either to pass around the oven or to pass more directly to the stack or jlue and to this end to provide a damper shifta'ble into positions which will prevent or permit the circulation of the products oi' combustion around the oven.

A still further object is to provide a stove of this kind with a removable lire box so that the lire box may be taken out and dumped when desired or the lire laid therein without the necessity ot reaching into the stove ttor this purpose.

Other objects have to do with the details ot construction and arrangement of parts to appear more fully hereinafter.

My invention is illustrated in the accompanying drawings wherein Figure 1 is a perspective view of a stove constructed in accordance with my invention; p

Fig. 2 is a longitudinal vertical section through the stove.

Fig. 3 is a longitudinal horizontal sec# tion on the line 3 3 ot' Figure 2;

Fig. 4 is a transverse section on the line 4-4 of Figure 2;

Fig. 5 isa fragmentary section through 192e. semi no. 122,260.

afcorner of the stove on the line 5 5 of Figure 1;

Fig. 6 is a fragmentary perspective-view or the damper plate 34. y

Referring to these drawings it will be seen that the stove is rectangular in i'orm and consists of a body which, as illustrated, is made of a single sheet oli' metal formed to provide a top 10, a bottom 11, and two opposite side walls 12, this single sheet ot metal being joined along the line 13 in any suitable manner. lt will be understood that while I. have illustrated a single sheet of metal as forming the body of the stove, it might he made of a plurality of sheets.

The top ot' the stove is formed with the upwardly extending thimbleA 14, upon whicha stack or flue may be mounted. The front end o'f the stove l5 and the rear end 16 are joined to the body of the stoverhy forming the forward and rear margins o'l1 the body with' a returned bend 16, see Figure 5, which extends parallel to the body oi` the stove and then the material is bent outward so as to rform a relatively large corner bead 17 and the edge of this bead is brought against the metal of the'iront or back sheet, as illustrated in Figure 2.

Both the front and back sheets and 1G have inwardly extending flanges 18 which extend inward against the outer face ofV the returned bend 1G, as shown in Figure 5. Thus, the sheets or sections which form the completed casing oi the stove are interlocled with each other' and engaged without thenecessity of any rivets. At the same time ribs are formed by the beads 17, these ribs extending across the stove at each end thereof and thus reent'orcing and protecting the joints between the top and bottom plates and the `l'ront and rear of the stove, as illustrated best in Figure 1. Corner pieces 19 are riveted. or otherwise attached to the corners of the ycasing so as to protect these corners from any deformation in handling the stove.

Disposed across the top oit the casing and attached to this top andextending to the end walls is an angle iron 20. Disposed rearward of this angle iron is the oven 2l. This is also lcomposed preferably of a single sheet of metal bent into rectangular form in cross section and has a length equal to the width of the casing. The walls of the oven are inwardly flanged `at 22 at one end and engaged over an inwardly projecting flange 23 fornied on one side wall of the stove and defining an opening to the oven. These flanges are riveted or otherwise engaged with the side walls of the casing and lie flat against these side walls. The oven, as shown in Figure Q, is spaced freni the top and bottom walls and the rear of the oven is spaced from the rear wall of the casing and, of course, the front wall of the oven is spaced a considerable distance from the front wall of the casing so as to provide a space 24 for the lire box.

Attached to the front warllot' the oven and extending transversely across the front thereof is a baille plate a5 which is parallel to `the front wall of the casing and shields the oven from the 'direct heat of the tire. The fire box may be permanently mounted within the stove Q4; but as illustrated the tire box 2G rectangular in cross section and is closed at one lend and is adapted to be inserted into the space 24 through an opening 27 inthe side wall. The open end of the tire box 26 is yprovided wlth a rectangular frame 2S which is slightly larger than the opening 27 and hinged to "this frame is a door which when turned upward, closes the opening 2T and fis vheld closed by any suitable latch. The front wall of the lire box is perforated at 30 andthe front wall of the casing is slotted at 3l and provided with 'a sliding damper En. Air 'will pass in through this vdamper and pass through the peryforations in the lire box and so gives sullicient air to the fire.

The opening of the oven is also closed by means of a door 33 hinged tothe casing below the lower wall of the oven and this door is also provided with a suitable latch whereby it may be held closed.

Operating over the top of the oven is a dani-per plate Bet which is angular in form so as vto provide a portion which rests upon the upper wall of the oven, an upwardly inclined deflected portion 35, and ay horizontal portion 36. The thinible 14- is disposed adjacent one corner of the stove and this damper plate when it is pushed forward, acts toprevent or nearly prevent the direct passage of the rproducts of combustion upward through the tine .and causes these products to pass downward and rearward in Ifront of. the oven and beneath the saine and then upward at the rear end of the oven and out through the flue. When the damper plate is drawn rearward, however, it will permit the direct passage of "theproducts o`t` combustion up over the front ot 'the oven and out through the flue and the degree of draft niay be controlled by adjusting this damper plate so that the inclined portion 35 will extend niore or less across the lower end of the flue.

The advantages of my improved stove are as follows :-'I`he ends of the stove are locked into the remainder of the body without rivets, bolts, or screws and this locking means reenforces the corners of the stove so that the stove is not liable to be deformed or otherwise injured in transportation or handling. The round corners 19 bolted, riveted or otherwise attached to the stove give protection when the stove is being packed on animals or in cars and both when in use or set up. The sliding draft plate 32 when closed will entirelyprevent lire dropping out of the st ve which is an absolutely necessary feature when the stove is used for camping purposes. 'lhe heavy angle iron 2() extending transversely beneath the top plate and almost immediately above the lire box keeps this top plate from warping. By having a removable tire box it is possible to remove the ashes without taking down the stove pipe.

It will, of course, be obvious that the stove may be made of different weights of sheet metal and it will be seen Vthat a stove constructed in accordance with my invention is very strong, compact, and -jnirticularly adapted for transportation on animals or by a wagon or by an automobile.

l. In la sheet metal stove, 'two plates disposed at right angles to each other, one of said plates being refolded upon the body o' the plate and then extended to forni a bead, the other plate extending between the end of said refolded portion 'and the bead and then being flanged to lit against the retolded portion to thus interlock the ltwo plates and form recnforcen'ients at the junction oi`Y said plates.

2. A stove of the character described, comprising a sheet metal body, rectangular in cross section, and end plates closing the ends of ysaid body, each end of the body being folded Vupon itselfand being extended in the forni of an arcuate l, ead,.each o the end plates having flanges extending inward into said trefolded portionsI and interlocking therewith, the beads having their outer edges engaged with the end plates and constituting reeuforcenlents for the corners of the body.

In testimony whereof I vhereunto allix my signature.
